Welcome Lisa and best of luck with your search. Puck L tend to be in shorter supply and usually sell at a bit of a premium. The benefit to some is the narrower width but to me the disadvantage is that many I see seem to have been overloaded, judging by how low they sit. You will probably find it easier to get a Pan or Familia. I'm guessing you are fully aware of the likes of Gumtree and Preloved for your search.
